From the author, winner of many prestigious literary awards, whose works have been published in 28 countries, film adaptation rights have been acquired for all of the writer’s books. Two years in the top 10 worldwide! 10,000 rave reviews on Amazon.com! An absolute book sensation of recent years! Everything was ready to celebrate the fifth anniversary of marriage, when suddenly one of the heroes of the occasion inexplicably disappeared. There were traces of a struggle in the house, blood that they had clearly tried to wipe off, and a chain of “keys” in a game called “treasure hunt”; a beautiful, intelligent and incredibly inventive wife arranged it every year for her adored husband. And it seems that these “keys” - the strange notes and no less strange trinkets she placed here and there - provide the only chance to shed light on the fate of the disappeared woman. But won’t the “hunter” have to reveal to the world a couple of his own unattractive secrets during the search?
